Additional information

I just thought of some further Additional Info. The machine I use this on is offline, I installed from a .deb. Spellcheck works just fine on my online ubuntu machine. Is it possible that spellcheck needs a connection to the internet at some point?

Ok this is not a bug. The spellcheck dictionary are downloaded on first use.

Thanks for the quick reply!

Can you post how you might setup spellcheck to work offline? Where to download the dictionary? Or, what qualifies for a dictionary? What folder the dictionary is stored?

This comes from electron/chrome and they use huspell dictionaries. The exact directory of where they are placed depends on the package format you chose.
